How this helps
Partials and “small items” jobs die on bad cube math: you accept three stops, show up, and the box is full after two. This tool totals volume and weight with a realistic packing factor so you can say no before you burn half a day.
It is an estimate, not warehouse software. Door height, couches, and pallet overhang still matter.
Common questions about cube fit
Is this a full 3D packer?
No. It estimates total volume and weight against your box and payload, then applies a packing factor for real-world gaps. Awkward shapes, door height, and load order still need your judgment.
Why use a packing factor?
Items never fill every cubic inch. A packing factor (this tool uses 75% of raw box volume as usable) keeps estimates honest so three “easy” stops do not overflow the box after two.
Does weight matter as much as cube?
Yes. A light, bulky load can max volume first; dense freight can hit payload first. Check both before you commit — especially on cargo vans and smaller boxes.
Is the cube fit checker free?
Yes — no signup, no card. It runs in your browser. Pair it with the free rate calculator once you know the freight fits.
